tpwpny 0 Posted January 6 Report Share Posted January 6 (edited) I am only getting SMP clouds when the Visual Effects setting in XP11 prefs is set to "High" or "Max" (HDR on) --which causes a massive FPS drop from about 35-40 to 18-20. Please advise. Edited January 7 by tpwpny Quote Link to post Share on other sites
sundog 615 Posted January 7 Report Share Posted January 7 Try changing the anti-aliasing settings in X-Plane, or use OpenGL mode. I think you're running into a known bug in AMD drivers when using Vulkan. Quote Link to post Share on other sites

I think you're running into a known bug in AMD drivers when using Vulkan. I'm not using Vulkan / Metal at all -- It's Mac, running XP11 in Open GL mode. GPU is Sapphire 580 Pulse/Nitro, 8GB VRAM, CPU is 3.46ghz 6-core, with XP on an internal SSD. Usual fps is 40-50. Quote Link to post Share on other sites
sundog 615 Posted January 8 Report Share Posted January 8 (edited) OK, I would still advise changing the anti-aliasing setting and see if that gets your clouds back with HDR off. Also, make sure you are using the latest version of SMP (4.9.3) Edited January 8 by sundog Quote Link to post Share on other sites

I'm using Ver. 4.9.6.2 Quote Link to post Share on other sites
sundog 615 Posted January 9 Report Share Posted January 9 Hey @Cameroncan you check that SMP is working OK on your Mac with HDR off? This is the first I've heard of this I think, but maybe you can repro it... Quote Link to post Share on other sites

I am running a Mac with an AMD 5700XT on the latest Big Sur. @tpwpny as drivers for GPUs are a part of the operating system with Mac, can you clarify which version of Mac OS X you're running?

Cameron 3,066 Posted January 11 Report Share Posted January 11 @tpwpny wish I could help you more! Unfortunately when it comes to Apple, we're at the mercy of their developers updating drivers unlike in the Windows and Linux worlds. I suppose the only chance you have is to upgrade, which I wouldn't blame you for not doing either (not that I've had any issues with Big Sur). Quote Link to post Share on other sites
